Transformer Mounting

The J6865 and J6866 mount transformers to the pole using hot dipped galvanized structural steel.

The TB mount is hot dipped galvanized ductile iron.

Description

MPS has designed its J6865 and J6866 one-piece triple transformer racks to make installation easier by making them lighter. These one-piece transformer racks can be assembled with transformers on the ground and then hoisted as a unit into position for mounting on the pole. The transformer racks include a welded lifting eye to facilitate hoisting the rack up onto the pole. The J6865 rack has 12" lug centers for mounting three, 3kVA through 50kVA transformers. The J6865 has a strength capacity of 2000 per position or a total of 6000 lbs for all three positions loaded simultaneously. Six 5/8" x 1-3/4" machine bolts are included for bolting the transformer to the rack. It is secured to the pole with two 3/4" machine bolts and two 1/2" lag screws to prevent the installation from wobbling in the wind. Holes are provided for a groundwire lug. The J6866 rack can be used to mount three transformers ranging from 75kVA through 333kVA (24" mounting hole spacing). The J6866 has a strength capacity of 5,000 lbs per individual position or a total of 15,000 for all three positions loaded simultaneously. Each position is designed to accommodate ANSI type "B" lug spacing. Six 3/4" x 2-3/4" machine bolts are included for bolting the transformer to the rack. It is recommended the rack be fastened to the pole with two 3/4" machine bolts and four 1/2" lag screws. Holes are provided on the rack for a groundwire lug. TB series cast transformer mounts feature a locking slot for a 3/4" diameter pole mounting bolt. The mounts can be installed on the transformer prior to installation of the assembly on the pole. They are furnished with two 5/8" diameter bolts, nuts and washers for attachment to the transformer. Accomodates maximum 4000 lbs. transformer weight. J6865 and J6866 are RUS approved.
